There is no interstate crossing between Kentucky and Missouri. That state border
meanders along the Mississippi River. I don't know the exact length, however.
There is also no interstate connection between Kentucky and Virginia.

None of the above. I broke out the GIS and found the following:
ID-KY: 180 miles
KS-NE: 365 miles
NE-SD: 435 miles
I just measured the length of the Michigan-Wisconsin border, across
which no Interstates cross, and it clocks in at 585 miles.
Can anyone beat 585 miles?

Such a state would have only intrastate Interstates, yes. There isn't

Further, there used to be almost no drivable connection between the two

Alaska and anyone - 3 or 4 thousand miles.
I'm bored this morning, so I'm taking a long look into the questions
you posed. Noting other responses already posted, the following is an
objective look at the questions:
> 1. What's the longest border between two states not crossed by an
> Interstate?
Here's a listing of the borders that qualify (in alphabetical order,
and excluding borders along the Great Lakes):
Arkansas-Louisiana (until I-49 gets built)
Arkansas-Mississippi (until I-69 gets built)
Colorado-Oklahoma
Georgia-North Carolina
Idaho-Nevada
Idaho-Wyoming
Iowa-Wisconsin
Kansas-Nebraska
Kentucky-Missouri
Kentucky-Virginia
Michigan-Wisconsin
Missouri-Nebraska
Montana-South Dakota
Nebraska-South Dakota
Nevada-Oregon
New Mexico-Oklahoma
New York-Vermont
After initial screening, I can narrow it down to these three:
Arkansas-Mississippi (due to significant meandering of the state border
following what was then the flow of the Mississippi River)
Kansas-Nebraska
Nebraska-South Dakota
Unfortunately, I don't have the resources available right now to
determine which one is the longest.
> 2. Which border between two states is crossed by the most Interstates?
The winner: Illinois-Missouri, with 7: 55, 57, 64, 70, 72, 255, and
270. Revive forgot about 64.
> 3. Which states have Interstates connecting them to every other state
> they border?
Since your criteria make only the Lower 48 eligible, there is actually
an even split amongst the Lower 48 between states that have Interstate
connections to every state they border and states that don't. The
states that don't are mentioned above in my answer to #1.
> 4. Which states have Interstates connecting them to no other state they
> border?
The way you worded this question, there is no answer, as every state in
the lower 48 has at least one Interstate that crosses its borders.
I agree.

Yes. Really its I-70 that serves no purpose. Wheeling is small town.
Building two interstates, no more than 3 miles apart at their greatest
distance of seperation, was the silly part of it. Name another town
that can be completly bypassed with a road only 3 miles away.
I-70 should have followed I-470's route, and I-70 should have never
been built. Today, 470 should be re-signed as 70 and 70 as a BL or US
highway. It doesn't meet I standards anyway.

Neither Alaska nor Hawaii is eligible, as neither borders any other
state.

If we decide that every US possession counts as a state, and that marine
borders are acceptable, then PR would actually be eligible as it borders
the USVI. EXCEPT, I did also rule out unsigned Interstates....
The original intent for Interstate Business Connections was NOT to
sign them along freeways in their entirety. In fact, how many busi-
nesses do you normally find along a freeway, anyway? None. So, it's
not really serving its purpose as a BUSINESS Loop if it has zero
access to any BUSINESSES.
It's a very few states who, IMHO, bastardized the Interstate Busi-
ness Connection over the past decade or two -- California, North
Carolina and South Carolina come to mind -- and started what I
believe is a bit of a problem.
Folks from NC, for example, who are used to seeing full-blown
freeways signed as Business Loops may start believing that ALL
Interstate Business Loops are likely to be high-speed through
freeway routes and when they visit other states who properly
sign their Business Connections, are sorely mistaken. Similarly,
when an out-of-state visitor visits NC and wants to get off the
freeway for gas, food or lodging (or simply to visit the down-
town/CBD of the city bypassed by the Interstate) finds themselves
on yet another freeway bearing little difference from the freeway
they just left!
The source of the whole problem is the unfortunate situation that
the FHWA has tightened their standards for Interstate design over
the years, leaving some states who are bypassing older stretches
of Interstate with a segment of highway formerly signed as an
Interstate but no longer eligible for such designation.
Personally, with so many grandfathered stretches of Interstate
out there, I believe a bypassed stretch of freeway which has been
part of the Interstate system for decades should remain and be
given the appropriate 3dI designation for the situation. This
would have solved the "freeway-as-Business-Loop" problems in
CA, NC and SC.
IMHO, of course...
Well, so much for that idea....
Agreed on just about everything you said, although I would point out
that Wheeling was bigger back in the planning days of the Interstate
system. My guess would be that that's why 70 was planned and built
through the city center via the island and the tunnel. Then, for the
obvious reasons, they had to come back later and bypass the tunnel -- it
was just a giant lack of foresight all around on the part of the WVDOH.
Were they planning and building all this stuff today rather than in the
50s/60s, you're absolutely right, 70 would be routed on the bypass and
the current island/tunnel route would probably be US 250.

Actually, the US 460 connection isn't that bad. It's currently a two-lane, but
in that location it follows a river valley so it isn't that bad.
The US 421 connection crosses a hill (it's not quite a mountain) but it's a much
gentler climb than, say, KY /VA 160.
US 23 was a steep mountain climb but it did have truck lanes, which made the
crossing easier. Once you got to the Virginia side, the road became four lanes
until Kentucky's four-lane opened in the late '90s.
And, of course, one connection (US 25E) has been eliminated completely with the
opening of the Cumberland Gap tunnel. Now 25E goes straight from Kentucky to
Tennessee.
>SP, I-470 does have a rather important /raison d'ĂȘtre/: bypassing the
>Wheeling Tunnel, which cannot be used by hazmat-hauling trucks or

This discussion reminds me of how much I hate I-70 in Wheeling, particularly the
lane restrictions for the tunnel and requiring traffic merging from westbound US
40/US 250 onto westbound I-70 TO COME TO A COMPLETE FRIGGING STOP BEFORE TRYING
TO ENTER THE INTERSTATE!!!!! (Yes, the caps were intentional...)
I'm not sure what you mean. Kentucky and Virginia are directly connected by
I-64, but there is about 180 miles of West Virginia between them. Is this what
you are referring to?

Perhaps he means that I-95 clips the District of Columbia while
crossing the Potomac and therefore does not "serve" it because one
cannot leave the interstate within D.C., so there is a direct
connection between first/last exits in MD and VA even though 95 does
not cross a VA-MD border.

Tight Interstate downtown bypasses, same general distance or closer:
Kansas City, KS/MO
Baltimore, MD
Portland, OR
New Orleans, LA
Denver, CO (I-270 plus part of I-76)
(*Not comprehensive lists*)
Both alignments of each enter the respective cities, but, then again,
I-470 itself does enter Wheeling.

Marc Fannin|musx...@kent.edu or @hotmail.com| http://www.roadfan.com/
This strays from the bypass qualification, but I-44 and US 40 <mumble>
/I-64 </mumble> are about a mile apart for a few miles west of downtown
St. Louis, which is pointless in a way. I-44 really should have been
put on one of the farther south alternative routes in the city, or both
routes should have been combined into a 16 lane Dan-Ryan style
facility.
Ohio has 6.69 miles of I-470, and West Virginia has 3.94 miles of I-470,
per the FHWA Route Log and Finder List for the Interstate Highway
System, so Ohio was an equal or greater stakeholder in requesting the
10.63 mile long I-470 bypass. It also bypasses Bridgeport OH.
The I-70 / I-470 complex at Wheeling was in the "Yellow Book", official
title _General Location of National System of Interstate Highways_,
September, published 1955, by the U.S. Bureau of Public Roads.
So the decision to build both routes was part of the originally approved
Interstate Highway System.

That's the one I meant. Any other examples of this? Maybe with a
non-Interstate route?
Doesn't I-86 do this twice? If it doesn't now, it will when it is
completed. I-86 will cross from PA to NY on its west end, and then
cross over to PA and back to NY near Waverly, NY.
-Michael P. Gronseth
Negaunee, MI
"Will" is the operative word here. I-86 still ends at Exit 52 at
Horseheads, pending completion of the "bypass-in-place" NYSDOT is doing
of the existing NY 17. (Basically, the new I-86 freeway will be built
above what is now the surface-road NY 17, with new service drives being
built at ground level next to the current ground-level NY 17.)
FWIW, something also has to be done with the eight-mile section
southeast of Elmira, between Exits 57 and 59, that still has at-grades.
Once these two projects are done, I-86 can extend at least as far as I-81.
Honorable mention (if I'm understanding correctly) : I-275, KY/OH (west
of Cincinnati). True, I-275 does have an exit in intervening Indiana,
for US-50, but I-275 doesn't actually cross US-50 until both are in
Ohio.
http://mapper.acme.com/?ll=39.13,-84.81&z=13&t=M
I think that another solution to the problem is to just sign the older
freeway with a state highway designation. Most of the larger states
have freeways that are not Interstates.
In fact, Business-80 in the Sacramento, CA area is officially
designated as two separate routes. The E-W portion paralleling W and X
Streets is at interstate standards and is unisgned I-305. It is also
officially designated as US 50 in the California state codes. US 50 is
also signed along the stretch, but the signs for Business-80 are more
prominent.
The N-S portion paralleling 29th and 30th streets has a section that is
below interstate standards. It is officially designated as CA state
route 51, but there are no trailblazers to that effect. (Several years
ago during a major construction project there were construction signs
that noted the road as CA-51, but they were small and easy to miss.)
This section is signed as Business-80 only.
An easy fix to Business-80 would be to remove the Business-80
designation entirely and have the E-W section become US 50 (and
unsigned I-305) and the N-S section be known as CA-51.
I'm not as familiar with NC and SC, but I imagine that those green
interstates could also be replaced with state highway numbers.
I-49 will eventually go AR-TX-AR.
When I went through that area a couple years ago, I thought that the
interchange should have been marked something like "IN-1 North TO U.S. 50"
Since if you do not turn onto U.S. 50 at the end of the interchange access
road, you are taken to SR-1.

I see your point, that SR-1 should extend to I-275. However, the .pdf
diagram linked from
http://www.in.gov/dot/pubs/manuals/interchanges/275.html shows
unambiguously that the 50/275 connection is considered as a long pair
of ramps, not as SR-1. Interestingly, the diagram also shows the
50/ramp intersection offset a bit from the nearby one, presumedly the
one with SR-1....

AR 176 in North Little Rock will fit this description soon once the new
ramps to I-40 are open.
